The short version

  • Only ConfigCat has a free tier, so it costs nothing to try first.
  • Each has a real cost: ConfigCat there is no experimentation or statistical analysis engine, so teams wanting real A/B tests with significance testing must buy and integrate a separate analytics or experimentation product.; WebStorm jetBrains WebStorm is sold as an annual subscription rather than a one-time purchase: commercial price is $199 per year (USD), and personal price starts at $299 in year one, dropping to $239 in year two and $179 from year three onward with continuous renewal.
  • They diverge on capability: ConfigCat covers Feature flags and configuration, WebStorm covers Smart JavaScript editor.
  • Prices and features above were last checked on 31 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

ConfigCat

  • There is no experimentation or statistical analysis engine, so teams wanting real A/B tests with significance testing must buy and integrate a separate analytics or experimentation product.
  • Pricing by flag count punishes exactly the hygiene you want: the Pro tier caps at 100 flags, so teams that do not aggressively retire stale flags are pushed to the 325 dollar Smart tier for housekeeping reasons rather than growth.
  • The free tier allows only 2 environments, which does not cover the common development, staging and production split, so almost any real deployment starts on a paid plan.
  • It is a smaller vendor than the category incumbents, so enterprise procurement teams will find less depth in compliance attestations, contractual terms and reference architecture than LaunchDarkly offers.
  • Flag evaluation relies on SDK-side caching of a CDN-delivered config, which is fast but means propagation of a change is eventually consistent rather than instant, something to understand before relying on it as an emergency kill switch.

WebStorm

  • JetBrains WebStorm is sold as an annual subscription rather than a one-time purchase: commercial price is $199 per year (USD), and personal price starts at $299 in year one, dropping to $239 in year two and $179 from year three onward with continuous renewal.
  • If the subscription lapses, use of new versions stops; JetBrains grants a fallback license only for the last version used while the subscription was active, per its published buy page.

Source
ConfigCat: Is the free tier usable?

For small projects yes, but at 10 flags and 2 environments it will not cover a dev, staging and production setup.

WebStorm: What is the cost of a commercial WebStorm license?

The page references a testimonial mentioning 70 euros as a cost, though specific current pricing requires visiting the dedicated pricing page.

Source
ConfigCat: Can it run A/B tests?

It can split traffic, but there is no statistics engine. You need a separate analytics tool to decide a winner.

WebStorm: How does JetBrains AI licensing work?

Users can pay with JetBrains AI credits, bring their own AI subscriptions and API keys to avoid vendor lock-in, or use the free tier included with WebStorm.

Source
ConfigCat: How fast does a flag change take effect?

SDKs poll and cache, so changes propagate on the polling interval rather than instantly.
